To wnoM IT MAYeoNcERN:

Be it 'known that I, ALEXeNDER McLEoD, of Covington, Kenton county, and State of Kentucky, have invented a certain new and usefutI Switch-Stand; and'do hereby declare the following to'he a fuii,elear, end

'exact description thereof, referenceb'eing had tothe accompanying drawings, making part of this specification.

This inventinrelates to a construction of switch-stand, target, and shot-bolt, with their accessories,whi'ch combines strength with security.V

The accompanyingdr'awing is 4a'perspective view of a switch-stand, a portion of the frame being removed. A A are two U-formed plates, constituting the framestand proper, secured to a sill or cross-tieQB. .C is

the target, attached to said stand, and bent backward at bottom, and attached to the sill B, 4so as to constitute a ve'ry e'ectual brace to the frame in addition to its proper functions. The two plates A A serve to. heid and guide 'th swtch-bar D, having two or more notches, d cZwcZ, according to the nurnber of positionsitis-` required to assun'ie. Cross-bars a u attached to the plates A A', and the target C, afford journal-bearings' 1,

for the switch-lever'E, which leveris pivot-boltedY to the switch-har, and surrncunted by a customary movable ltnrgetfe.' F is a shot-bolt, restricted to vertical play by suitablevguides, a a, in the fra-me. The said .shotbolthas a projecting tongue,f, which is subject to the Ydownward pressure of aspiral spring, G, and to the .up'ward pressure (which it is desired to retract the bolt) of-a pedal, H. The said bolt Fhas also, Ijust below its Iupper guide, an orice,rf, for a padlock, I, hywh'ich the boit may be secured against mischievous or accidental 4 misplacement, and s this lock cannot be applied, save Awhen the boit is in one or other Vof the notches, thc switchman is always made-aware ofsuoh unsafe condition of theapparatus. The shot-bolt may be surmountcd 'by a weight, J, to act either in co-operatiou with or in substitution of the spring G.

Y I claim herein as new, and of my invention- The arrangement of stand A A/a a', target G CVswitchbar D, lever E, shot-bolt VEff', pedal H, andY spring G, or Weight J, as and for the purpose s'ctforth.

In testimony of which invention, I hereunto Set my hand.

ALEXANDER McLEOD.
